RESEARCH METHODOLOGY

Detailed explanation-1: -Test or experimental constants are values that do not change either during or between tests. Numerous common powers and properties, like the speed of light and the atomic weight of gold, are experimental constants.

Detailed explanation-2: -A control is a variable that must be held constant so it won’t influence the outcome of an experiment.

Detailed explanation-3: -The controlled variables are quantities/items that you want to remain constant, and must observe them as carefully as the dependent variables.

Detailed explanation-4: -A control variable (or scientific constant) in scientific experimentation is an experimental element which is constant (controlled) and unchanged throughout the course of the investigation.
